"Yo' momma's so fat, she gotta take two trips to haul ass!"

"You so dumb, you think Taco Bell's a Mexican phone company!"

"Yo' momma's got so many crabs, she walks sideways!"

"Playing the Dozens" is an old competition between two people who engage in verbal sparring, or "ranking on each other", until one person can no longer retailiate. Each person comes up with a "snap", a humorous insult, trying to out do the other. Sometimes it escalates into physical violence, though it's mostly a verbal test of strength, having its roots in African American history.

Topps, Inc., the maker of sports collectible cards, released a new set of cards based on "Playing the Dozens". The set of 100 cards featuring snaps written by the Wayans Brothers, Marlon, Shawn and Keenan Ivory, with illustrations.
